Warner Bros. released the second ‘Tenet‘ trailer on Thursday, much to the delight of Christopher Nolan fans across the world.

Nolan’s latest film stars John David Washington and Robert Pattinson, and while details surrounding the plot have been few and far between, the studio did release this plot synopsis…

John David Washington is the new Protagonist in Christopher Nolan’s original sci-fi action spectacle ‘Tenet.’

Armed with only one word—Tenet—and fighting for the survival of the entire world, the Protagonist journeys through a twilight world of international espionage on a mission that will unfold in something beyond real time.

Not time travel. Inversion.

What the hell does that mean? No idea. And why are they calling Washington’s character “Protagonist”? Is that his actual name in the film? If so, does that mean the movie is a story inside a story?

I don’t know. They obviously wanted the synopsis to be vague, so I’m not going to attempt to make sense of it.

In any event, check out the new trailer below. And yes, the release date is still scheduled to hit theaters July 17, but that could change.
